Charbax | Eye-glow Attenuation AR Waveguides, National Yang Ming Chiao Tung University Hsinchu Taiwan, Paper @charbax | Uploaded May 2024 | Updated October 2024, 1 week ago.
The presentation revolves around "Eye-glow Attenuation AR Waveguides" by researchers from National Yang Ming Chiao Tung University in Hsinchu, Taiwan. The discussion begins with introductions, leading into the essence of the topic. CH, a member of the team, delineates their focus on designing distortion-free formulas for ideation in defective AR waveguides, particularly aiming to diminish eye glow, which refers to the leakage of light. They illustrate this concern with an image comparison, showcasing the stark contrast between a clear eye view and one marred by excessive eye glow, emphasizing the impact on user experience.

Questions arise regarding the feasibility of completely eliminating eye glow, to which the team responds by highlighting their efforts to reduce it rather than eradicate it entirely. They delve into the technical aspects, discussing the role of the glass shape in front of the waveguide and measures taken to prevent light leakage. Adjusting the grating profile emerges as a strategy to mitigate eye glow, prompting inquiry into the degree of reduction achieved. The team presents their findings, boasting a 46% efficiency in light transmission with only 15% eye glow, surpassing traditional binary gratings' performance significantly.
The conversation transitions to the importance of waveguide design, particularly in the context of AR glasses, with emphasis placed on the impact of reduced eye glow on user experience. Images are referenced to demonstrate the superior performance of the Meta gring in minimizing eye glow compared to traditional counterparts. The discussion further explores a freeform met example, highlighting its unpredictable yet effective design for eye glow attenuation.
The team shares insights into their lab's manufacturing capabilities for AR glasses, including measurements of characteristics like field of view. Images of their design are showcased, illustrating the integration of an image into the glasses. Gratitude is expressed towards collaborators for their contributions, including providing DLP and light images. The conversation closes with speculation on the future of AR glasses, acknowledging the ongoing advancements needed before widespread adoption. Overall, the presentation underscores the significance of mitigating eye glow in enhancing the AR experience and hints at the evolving landscape of AR technology.
